' AUTOMATIC WEFT-R-EPLENISH-ING LOOM. 1

I '0 all whom it may concern.

die it 'known that I, HORAC VVYMAN, a citizen of the United States, \Vorcest'er, in the county of lVorcester and Massachusetts, have invented certain new and useful Improvements in Automatic lVeft-Replenishing Looms, of which the following is a specification.

My invention relates to an automatic weft replenishing loom, and particularly to that class of looms which have a magazine at one end of a loom with a plurality of guideways or compartments for bobbins or filling carriers, and shifting or change shuttle boxes at the other end of the 100m for shutties with filling of different colors or characters, corresponding to the filling in the difl'erent compartments of the magazine.

The objectof my invention is to improve residing at- Specification of Letters Patent. Application filed May 12, 1908. Serial No. 432,463.

upon the construction of looms of the class referred to, and my invention consists in certain novel features of construction of my improvements as described.

In my improvements I provide a stationary magazine having a plurality of guideyvays or compartments for superposed fillwill be hereinafter fully;

ing carriers, which drop down by gravity in the magazine. I also provide a movable magazine located below the stationary magazlne, and preferably having a rocking or? swinging motion in the arc of a circle; said movable magazine is provided with the same number of compartments as the magazine, and each compartment stationary 2 has a discharge opening on its hnderside, and is adapted to hold only a single bobbin or fillmg carrier,

and each compartment is adaptedto. register with, or be moved into aline- :Inen't with atompart'm ent in the stationary bobbme emfilhng carriers m agazine having of the same color or character as the bobbin or filling carrier in the single compartment in the movable magazine, so that the lowest bobbin in a compartment 'inthe stationary magazine may be conveyed into the correspending compartment in azine at the proper time. With the stationary magazine and the movable magazine, I

combine a transferrer for transferring a bobbin or filling carrier from the movable magazine into the active shuttle, to take the plaro of a substantially or practically exhausted shuttle, said transferrer is preferthe movable magoperating Patented tlonary magazine, between two'pa'ins -of zine, and extending over the stationary shuttle box at the magazine end of the 19013 wh'enthe lay carrying said box is in its'fo'rtime. I also provide mechanism to move the movable magazine under the stationary magazine, to bring under the transferrer any one of the compartments in the movablemagazine which has a bobbin or filling carrier therein of the same color or'charac-' ter as that in the active shuttle, and to reably located at the central part of'tl1'e sta July 16, 1-912;- 1

"ward position. I provide mechanism for the transferrer' at the proper,

turn the movable magazine to its normal posit-ionfor replenishment from thestationary magazine, after the bobbin or filling carrier has been transferred into the active shuttle.

-. In the stationary magazine each guideway or compartment for the bobbins or fill ing carriers has movable retaining mechanism at its lower end for the lowest bobbin or:

which mechanism is operated 5 I at the proper time to release said bobbin and allow it .to drop intothe corresponding comfilling carrier,

partment inthe movable magazine, and each compartment of the-movable. magazine has movable retaining mechanism for its bobblnor filling carrier.

The mechanism for transferring the bobbins or filling carriers from the movable magazine into the active shuttle, lspreferably made adjustable,' and independent of the movement of the lay so that the transferrer may be operated wi extreme forward position and is commenc- 1611 the lay is at its ing its return movement, so as'to obtain more time for the detector to act after the shuttle has'enteredth'e shuttle box under the magazine. I

In my improvements as shown and described herein, the filling detecting mechanism for detectingthe practical or substantial exhaustion of filling in the active shuttle; is.

located at the-magazine end of the loom, and

is actuated when the shuttle is at the magazine end'of the I oom,.and the transfer of the bobbin or filling carrier takes place imme Y operation of the fillllLQ dcdiately upon the tecting mechanism, without the shuttle being thrown to the opposite side of the Imam and returned to the magazine end, as is customary, and the detection and the transfer of the bobbin or filling carrier occurs'o-n the forward movement of the lay, and during the time the active shuttle is under the transferrer.

The filling detecting mechanism shown in the drawmgs'corresponds to-the filling detecting mechanism shown and described in' the Letters Patent of the United States, No.

939,696. I have only shown in the drawings a detached portion of a loom of the class referred to, with my improvements applied thereto, suflicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :Fi'gure 1 is a detached end view of parts of a loom frame with my improvements applied therezine, on line 4,,4, Fig. 3, looking inthe direction of arrow b, same figure. Fig. 5 shows the transferrer mechanism, and a part of the:-

movable magazine the parts are shown in the position they occupy when a bobbin or filling carrier is being transferred. Fig. 6 is. a planview of the stationary magazme,

and some parts connected therewith, look upper ends ing in the direction of arrow 0, Fig. 1.

In the accompanying drawings, 1 is the loom side or end frame, 2 the loom arch, 3 the lay, 4 the lay sword, pivoted at its lower end, 5 the crank connector to the crank shaft, 6, 7 the bottonr shaft, 8 the stand for the stationary magazine, 9 a single shuttle 'box on the magazine end of the lay, 10 a shuttle in the box, and 11a bobbin or filling carrier in the shuttle.

-All of the above mentioned parts may be 7 of the usual and well known construction.

The stationary magazine in this instance consists of the inner or back plate 12, having side extensions 12 bolted to the stand 8, and having four vertically extending guideways or compartments 12- for the heads of the bobbins 11, and front plates 12 connected by rods 12 with the side ears or extensions 12, and having vertically extend-' ing guide-ways or compartments 12 therein for jthe tips of the bobbins 11. T he transferreriis located'in this instance at the central part ofthestationary lnagazine, and between the two pairs of. guide-ways or compartments for the h0bbins,\ and consists in this instance of a vertically-extending rod 13, guided-in bosses: or prpje'ctions 12 on the plate 12. The lower'end 'oi-said rod 13 is provided with a horizontally extending arm 13, which extends over a bobbin or filling carrier 11 in the movable magazine, to

be hereinafter described, to transfer said. bobbin into the active shuttle.

-coile'd expansion spring 13 encircles the rod A helically 13, and bears at one end against the lower projection 12" on the plate 12, see Fig. 4,, and at its upper end against a collar 13 on the rod 13. The spring 13 acts to raise the transferrer 13 and maintain it in its raised position above the filling carriers in the movable magazine. On the rod 13,.near its lower end, is a pin 13', which in this in-f stance extends rearwardly from the rod 13' through an openlng in the back plate 12 of Y.

the magazine, see Fig. 4, and into an open end slot 14 in the lever 14 for the trans ferrerrod 13'. The lever 14 is pivoted at 15 'on the stand 8, and has the downwardly ex- "tending arn'r14, through which the transferrei' lever or arm 14 is, operated, in the manner to be hereinafter described.

The lowest filling carrier 11 in each compartment or guide-way of the stationary magazine, is retained in position, in this instance at its head and tip end, by two re 'taining. hooks 16, see Fig. 4, on a plate 16 having bosses l6 loosely mounted on a pin.

17 and having in this instance a projection 16' thereon, see Fig. 3, which extends in the path of and is adapted tobe engaged by the lower hooked end 18 of a vertically extending rod 18. The rods 18 have a hearing in a projection 12 on the back plate 12,

see Fig. 4, and are bent inwardly at their and extend through elongated openings 12 in the plate 12, The mechanismfor operating the wrist-18 will be hereinafter described.

I will now describe the movable, or sup-v plemental magazine, The movable magazine is located below .the stationary magazine, and consists in this instance of a plate 19 having four guide-ways or compartments 19, corresponding to the number of guideways or compartments in the stationary magazine,-arid" each guide-way or compartment 19 holds a single bobbin or filling carrier 11. The plate 19 is in this instance of arc shape and of a curvature corresponding to the curvature of the lower end of the lot stationary magazine, and is supported, to

have a rocking or swinging movement under the stationary magazine, by an arm 20 having a hub 20 at itsupper end which is loosely mounted on a stud 21, in this instance on the stand .'8 of the stationary magazines Extending out from the front side of the plate 19, at the lower end of the compartments 19, is a'series of fingers or supports 22, each pair of which are preferably spring pressed toward each other in any suitable manner, to yieldingly hold a bobbin or filling carrier 11 in each compartment,

preparatory to being'trahsferred by, the ferrer,

. shuttle is in operation; the arm 27, as it assumes the different positions of the dotted transferrer into the active shuttle. The fingers or supports, 22, of which there are two for each discharge opening, one at each side thereof, are pivotally mounted, or: fulcrumed, on: pins, to have a rocking motion,

and normally held in operative position by springs, not shown, and having their depending ends inclined toward each other, so'that when a filling carrier is pressed downwardly by thet'ransferrer, they open with :an equal resistance at each side, and guide the filling carrier into the the direct line of'movement of the transferrer. Instead of having the fingers or supports 22 contact with the filling -.on the carrier, they may be constructed or shaped to contact with the tip and head ends, respectively, of the bobbins.

I will now describe the parts constituting the means for moving the supplementary magazine to and fro 'under the stationary magazine, to convey a bobbin, which been received from the stationary magazine, to its transferring ferrer. On the arm is a stud23, 4, to which is connected one endof see Fig. a. rod vor connector 24; the other end of the connector 24 is connected with a studa25 on a vertically moving slide 26, which is mounted in a vertically extending slot 27 in an arm 27, which extends out from and forms a part of a lever 28, see.Fig. 6, which lever has its hub 28 loosely mounted on a stud 29 on the loom side. The slide 26 is retained at the upper end of the slot 27 in the arm 27, by a latch 30 pivoted on a pin 30 secured to.-the farm 27. The'latch 30 is notched at its upper end to receive the lower end of the slide 26, and has a downwardly extending end 30f, the lower end of which is in substantial alinementwit-h the fulcrum of the lever 28. A spring 31 is attached at one end to the extension 30", and at its other end to the arm 27, and acts to yieldingly hold the latch 30 in engagement with the slide 26. The lever 28' has a slot 28 therein, which is adjustably secured to the lower end of a rod or connector 32; the upper end of the connector 32 is connected with a lever 33, see...Fig. l, the hub 33 of said lever'33 is pivotally mounted on astudon the loom arch 2; An arm 33", extending out from the hub 33 is connected, through intermediate connections,not shown, with the shuttle box motion on the opposite end of the loom, so that the shifting, or risingand falling of the shuttle boxes, will, through intermediate connections to the 'lever 33, and

througlithe connector 32, lever 28, arm 27,

slide 26, and connector 24 to the movable magazine 19, move said magazine to bring a filling carrier having filling thereon of a color or character corresponding to the filling in the active shuttle, under the transshuttle in has.

position under the trans and maintain it there while the same lines 27, Fig. 1, moving the magazine to its different positions. The stud 25 on the slide 26 has connected therewith, the upper end of a second connector or rod 34; the lower end of said rod 34 is pivotally connected to a cam lever 35, which is loosely mounted at one end on a stud 36 on. the loom side, and has an extension "to which is attached one end of a'helically coiled contraction spring 37. The inner end of said. spring 37 is attached to a stand 37 on the loom frame. The spring 37 acts, through lever-35 and the rod 34, to. move the slide 26 down when it is disengaged from the latch 30, see Fig. 3. The cam lever 35 carries a roll 38 which travels on the periphery of, and in the cam groove 39 in a cam 39, fast on the bottom shaft 7. A'revolution of the bottom shaft-7 and the cam 39, acts to raise the lever 35, the rod 34 and the slide 26 to their normal raised position, shown in Fig. 1, whenever the slide has been lowered, by disengagement of the latch 30 from under it. To the downwardly extending arm 30 of the latch 30 is con nccted one end of a rod 40, the other end of said rod 40 is pivotally connected with one arm of a lever 41, centrally mounted on a stud 41 on the rear side of the rear plate 12 of the magazine, see Fig. 5. The other arm of the lever 41 extends in the path of and is adapted to be engaged by the open slotted end 14 on the transferrer lever 14, and

when the transferrer lever 14 is operated to move down the transferrer'13 to cause it to transfer a bobbin from the movable magazine into the active shuttle, the lever 41 will be rocked or moved, and through rod or connector 40, will move the latch 30 away from and out of engagement with the slide 26, and allow said slide, through the connector 34 and cam lever '35, .to be moved downwardly in the slotted arm 27,to bring the stud 25 in said slide intoalinement with the fulcrum stud of the lever 28, as shown in Fig. 3, to move, through connector 24, the supplemental magazine 19 to'its central position, shownin Fig. 3, to cause the compartments in said movable magazine to register with the compartment in the stationarymagazine.

The downward movement of the lever 35,

through the rotation of the cam 39, acts,

through rod .42 connected at its lower end to said lever 35, and atits upper end to an arm 43, see Fig. 6, having its hub 43 fast. on a rock shaft 44, to raise said shaft and with it a plate or bar 45, having its hub 45 fast on said shaft 44, and opened' end slotted portions 45" thereon,

see ig. 4, into which extend the rearwardly extending upper end 18- on the vertically having three moving rod 18, to raise said rod, as shown at the right in Fig. and cause the lower end away from the bobbin, as shown in Fig. 3,-

thercof to 11-11211 off from the projections 16' on the plate 16" of the retaining hooks 16, to allow the hello-ally coiled contraction spring 16 to operate tomove the hooks 16 and allow the lowest bobbin 11 frdm a com- 'partment in the stationary magazine, to

drop downinto theco-mpartme'nt register- I ing therewith in the movable magazine, to

tically moving rod 18 which is' to be operated.

take the place of the bobbin which has been transferred into the, active shuttle.

To select the vertically moving rod 18 which has to be operated to release the hooks.

16 which retain the bobbins in the compartments in the stationary magazine, I employ in this instance a rocking rod 44, which also has a longitudinal movement in suitable I bearings 44 on the stand 8. The rod 44 has a hub 44 on one end thereof,- with an annular groove therein, into which extends a pin 46 on one armof a bell crank lever 46, which is pivotally mounted on a stud 47 on the stand 8, see Fig. 1. The other arm of the bell crank lever 46 is connected by a rod 48 to an extension 27" on the slot-ted arm 27. The longitudinal movement of-the rod 44 will bring the plate 45, having the engaging ends thereon, in such a position that one of the engaging ends 45" will be in a position to engage the upper end of the ver- The continuedrotationof the cam 39 will, after the movable magazine has been replenished from the stationary magazlne, as

' above described, move the lever 35, and

' in this instance of a movable lever or bar 49, having a forked end 49' at its inner end to receive the crankshaft 6, and carrying on said end a roll 50 md'uiite'd bii a stud 50', which roll extends in the path of and is operated by a cam 51 fast on, the crank shaft 6, see Figs. 1, 3 and 5, to move said bar with an intermittent movement, substantially coinciding with the forward movement of the lay, when the active shuttle is at the magazine end of the loom. The outer end of the bar-49 is guidingly held and supportedin a stand 52 secured to the loom side. The bar 49 lias an upward extension 49' thereon oarryiiiga stud 53, on which is pivotally mounted a two armed lever 54, which has a'movement in a horizontal plane, and has its outer arm adapted to engage the dog 14 on the arm 14", to move the transferrer arm 14 and to operate the transferrer 13. The other arm of the lever' 54' extends in the path of and is adapted to be engaged by a rod 55, which extends forwardly from the front of the lay and is pivotally mounted on a stud56 at the rear of the lay,to have a movementin a horizontal plane. The lever 55 has a rearward extension '55 thereon which has connected thereto one arm of a lever56 having a hub 56, which is pivotally mounted on a stud 57 on a stand 58 secured to the back of the lav. 'The other arm of the lever 56 is pivotally attached to an extensi'on59- on the filling detctor. 59, which is pivotally mounted on a pin 60 at therear of the stationary shuttle box, and is adapted to feel through an opening in-the shuttle box and in the shuttle, to engage with the filling on the bobbin. Q

In case there is a supply of filling on the bobbin, the filling detector 59 is held by the filling in its outward position, and through connectionsto the lever 55, the lever 55 is held in the position shown by broken lines in Fig.2, and out of engagement with the lever 54, so that said leverwill not be moved into the path of the extension 16 on the t-ransferrer arm 14," but if the filling on the bobbin is substantially exhausted, as shown in Fig. 9., then the fillingdetector 59wi11 be moved inwardly, and through connections to the lever 55, will move said lever into the position shown by full lines"in"'Fig. 2, and

cause it to engage the lever 54*to move the end thereof into the path of the-extension 14 on the transferrer arm 14, so that the forward movement of the bar 49, through the engagement of the cam 51' wit-lithe roll 50,, will operate the transferrer arm 14, and through the movement of said arm will operate the transferrer 13, to transfer a bob-bin from'themovable magazine into the active shuttle, all as will befully understood by those skilled in the art. By turning the cam 51,-which is adjustably mounted on the shaft 6, the forward movement of the bar 49 can be adjusted so as to operate the transferrer arm during any portion of that movement of the lay, either before, or after its extreme forward movement, in which the magazine may be placed, to transfer a filling carrier into the shuttle on the lay. The arm 14, rod 13, and parts intermediate said arm and rod, maybe termed a transferrer.

In my improvements, the movable magazine which receives the bobbins from the stationary magazine and conveys them to a position under the transferrer, may be termed a bobbin conveyer. And the parts,

embracing the pivoted lever having an arm movable back and forth responsive to the movements of the shuttle boxes, the movable slide carried by the arm havlng a connection to .the bobbin conveyer,.the cam on the position of said arm to its axis, to cause the bobbin ,conveyer to remain stationary, may

- be termed a bobbin conveyer actuator. This bobbin conveying actuator is applicable also to a movable bobbin conveyer underthe stationary one, in which there is onecompartment only, insteadof one for each of the compartments of the stationary one, this one compart-meutbeing normally without a bobbin, but registering with one or another of the compartments of thestationary one,

brings a shuttle of one or another color of filling-into activeoperation on the lay, and p which, upon an indication for a chan e of mam-n, andith'enceconveyed to the transhlling, will immediately cause a bobbin to he dropped into themovable compartment v.feri-ingposition under thetransferrer, in this instance, the pOSll-IODOf the cam 39 on the shaft will be so timed that the transfer of the bobbin'willtake place when the stud or pin will be at its neutral position, as in Fig. 3, and having the bobbin immediately under the transterrer.

to hold all of the bobbins in their respective compartments,'nntil the indication occurs to release the one to fall into the movable combartmcnt under it.

' Itwill hcnnderstood that the details of any ordinary construction of my improvements may be varied if desired, and my improvements are L dapted to be used stop motions, (lobby, or jacquard motions,

and any other ordmaryloom mechanisms.

The filling detecting mechanism may be of the breast beamnnstead of on the lay, if

preferred.
